Gotta remember that doing headers is a huge PITA on the 5.4 tho. Unless you have a welder you are more than likely gonna have to take it to a shop to get out broken studs. So that's more money there to. Unless you drill them out you can do that too

If I do get headers I'll take the whole exhaust off except for manifolds, go to a shop and have them take the manifolds off, install the headers and weld up a new exhaust but with a clamp at the header collectors so it can be removable. I'd run true duals into two magnafleo high flow cats then into a magnaflow DI/DO muffler then exit lightning style.

I had similar plans and almost pulled the trigger on it. 2.25 inch duals with chelsey pipe high flows long tubes and magnapacks. But then I realized that if and when I built my engine and go supercharged I will have to get a bigger exhaust.So that's why I didn't do it. But it's a good plan tho

You're just supposed to weld to the collectors then bolt them up
